Fresh lens feeling and end-of-day comfort( using LACREON™ technology that permanently embeds a water-holding ingredient, similar to that found in natural tears)

Dk/t value : Oxygentransmissibility of a contact lens. In general,the higher these values are, the better is the oxygen transmissibility of the lens. The high level of oxygen flow to the cornea is important as it improves wearing comfort and longer term tolerance

Water content : Contact lenses with a lower water content dehydrate less on the eye than do lenses with a high water content, so they could be better for people with dry eyes. Contacts with a high water content usually have a higher oxygen transmissibility. Therefor they are more suitable for longer wear.
